Hello,
2019 F350 Lariat 6.7l Power Stroke. 193k miles.
I have tried searching through the forums for similar threads to this and have found a couple that are close, but nothing quite matches what I have going on and I am wanting to see if I can get any insight on my situation.
I have not owned this truck for an incredibly long time. I purchased it with a little over 170K miles on it. The previous owner has good maintenance records for it.
Just over the last week I have had issues with the Low Fuel Pressure warning light coming on. Always at lower RPMs or at an idle. I have checked for fault codes every time that it has come up and there is nothing on the system for fault codes at all. I have the Torq app and have run several logs while driving to keep an eye on things, but to be quite frank, I am not entirely sure what I am looking at. I am not sure that the pressure is supposed to be. There are a couple times at idle or low RPM that the fuel rail pressure dropped below just under 200PSI, but that is the lowest that I have seen. I can provide a link to the CSV files if anyone would like to take a look at them.
The truck doesn't feel like it has lost any power and it sounds the same as it always has. I changed out both of the fuel filters about 10k miles ago, so I was thinking that might be the culprit, but I thought those filters were supposed to be good for 15k miles.
I am not sure where the fuel pressure sensor would be at to change it, either. Does anyone have a part number so I can look it up?
Any insight would be greatly appreciated.
Thank you very much!
